Enhancing the Performance of MXenes and MBenes-Based Materials for Maximized Efficiency in the Oxygen Reduction Reaction

IGI Global eBooks, Journal Year: 2025, Volume and Issue: unknown, P. 171 - 202

Published: April 8, 2025

MXenes and MBenes, advanced two-dimensional materials with outstanding structural electronic properties, are gaining prominence in energy conversion storage, particularly for the oxygen reduction reaction (ORR). ORR, essential fuel cells metal-air batteries, suffers from sluggish kinetics, efficient catalysts. While noble metals like platinum excel this role, their high cost scarcity necessitate alternatives. MXenes, consisting of transition metal carbides, nitrides, or carbonitrides, exhibit metallic conductivity tunable surface chemistry, making them ideal ORR catalysis. Similarly, nitride-based analogs, show great promise. Optimization methods selective etching, functionalization, heteroatom doping significantly enhance catalytic performance. This review explores synthesis, structure, mechanisms highlighting recent progress, addressing stability scalability challenges, identifying future directions improving efficiency sustainable applications.
